Abstract : The technical manual describes the Digital Recording and Playback Equipment (DRAPE) and provides information necessary for operating that equipment and maintaining it in an operable state. The DRAPE acquires both analog and digital data from multiple sources and converts them to serial PCM signals which are then recorded on magnetic tape. To ensure that it is operating correctly and that valid data are being acquired, DRAPE recovers the data immediately after they are recorded and converts them to analog signals. These signals may then be applied to a recording device for monitoring purposes. Prior to the acquisition of data, header information may be entered through switches on the front panel and recorded to aid identification.
